Event description:
We consider the problem of defining a monoidal functor on the
category of framed tangles whose restriction to links is an
evaluation of the Kauffman bracket. We show that a very large class
of such functors correspond to bilinear forms with certain asymetry
properties. This gives us an insight into why categorifications of
the Bracket work they way they do.
